The Science Definition Of Isotope

One of two or more atoms having the same atomic number but different mass numbers.

The science definition of isotope. 10 people chose this as the best definition of isotope. Every chemical element has one or more isotopes. The initial isotope is called the parent isotope while the atoms produced by the reaction are called daughter isotopes. One of two or more atoms.

More than one type of daughter isotope may result. An atom is first identified and labeled according to the number of protons in its nucleus. The mass of a neutron is almost identical to that of a. What is an isotope.

Iso greek topos place so called because the isotopes of a chemical element occupy the same position in the periodic table of elements i so top ic tŏp ĭk adj. There are 275 isotopes of the 81 stable elements in addition to over 800 radioactive isotopes and every element has known isotopic forms. For example an atom with 6 protons must be carbon and an atom with 92 protons must be uranium. In addition to protons the atoms of nearly every element also contain neutrons.

Isotope one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Elements are defined by the number of protons in the atomic nucleus. Isotope definition any of two or more forms of a chemical element having the same number of protons in the nucleus or the same atomic number but having different numbers of neutrons in the nucleus or different atomic weights. As an example when u 238 decays into th 234 the uranium atom is the parent isotope while the thorium atom is the daughter isotope.
